I installed a fiberglass sink in my kitchen and one side is stained and has small hair line cracks. The other side that I had my dish rack in looks like new. I always clean my sink and not with any abrasive cleanser. I never left any thing like coffee or soft drinks lay in the sink after they were poured out. I was wondering if there is an easy way to remove a sink that is installed with an adhesive it seems that the only thing that is holding up. I cannont find my paper work to call the manufacturer. What do you suggest?
